Review PUROLATOR Crankcase Breather Smog Filter fits ELEMENT

The **Purolator B23124 Crankcase Breather Element (Smog Filter)** is a high-performance, precision-engineered air filtration solution designed specifically for modern vehicles equipped with positive crankcase ventilation (PCV) systems. This essential component plays a critical role in maintaining engine efficiency, reducing emissions, and protecting internal engine components from harmful contaminants. Crafted from high-quality, durable materials, the B23124 features a tightly woven, pleated filter media that effectively captures oil vapors, particulate matter, and other pollutants before they escape into the atmosphere. Unlike standard crankcase breathers, this smog filter is engineered to meet stringent emissions regulations, ensuring compliance with environmental standards while optimizing engine performance. Its compact yet robust design allows for seamless integration into the vehicle s PCV system, minimizing airflow resistance while maximizing filtration efficiency. The filter s advanced construction also helps prevent oil leaks and sludge buildup in the crankcase, contributing to longer engine life and reduced maintenance requirements. Whether installed in high-performance vehicles or everyday commuters, the Purolator B23124 ensures cleaner air, improved fuel economy, and a quieter, more reliable engine operation. Built to withstand the demands of modern automotive environments, this smog filter is a dependable choice for drivers seeking both environmental responsibility and engine protection.

**Pros and Cons of buying a Purolator B23124 Crankcase Breather Element (Smog Filter)**

The Purolator B23124 is a popular crankcase breather element designed to filter oil vapors and contaminants from an engine s crankcase, helping maintain clean air emissions and engine performance. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **Compliance with Emissions Standards**

The B23124 is designed to meet or exceed modern smog check requirements, particularly for California and other states with strict emissions regulations. This ensures your vehicle passes inspections without modifications.

2. **Protects Engine Components**

By filtering oil vapors and particulate matter, the breather element prevents contaminants from entering the intake system, reducing wear on the engine, intake manifold, and catalytic converter. This can extend the lifespan of these components.

3. **Prevents Carbon Buildup**

Without a proper breather filter, carbon deposits can accumulate on intake valves, pistons, and spark plugs, leading to reduced performance and fuel efficiency. The B23124 helps mitigate this issue.

4. **Easy Installation**

Purolator products are generally designed for straightforward installation, often requiring no special tools. The B23124 fits standard crankcase breather systems and comes with clear instructions.

5. **Cost-Effective Maintenance**

Replacing the breather element is a relatively inexpensive part of routine maintenance compared to the potential cost of repairing engine damage caused by unfiltered crankcase gases.

6. **Compatibility with Common Engines**

The B23124 is widely compatible with a range of vehicles, including many Ford, GM, Chrysler, and Toyota models from the late 1990s to the 2010s. Checking your vehicle s service manual or Purolator s compatibility list ensures a proper fit.

7. **Reduces Oil Consumption**

By preventing oil from being drawn into the combustion chamber through the breather system, the filter helps maintain proper oil levels and reduces oil burning, which can improve fuel economy.

8. **Durability and Longevity**

Purolator is a trusted brand known for producing durable filters. The B23124 is typically made from high-quality materials that resist clogging and degradation over time, especially when replaced at the manufacturer-recommended interval (usually every 30,000 60,000 miles).

### **Cons**

1. **Replacement Frequency**

While the B23124 is durable, it is not a permanent solution and must be replaced periodically. Neglecting this can lead to clogging, reduced efficiency, and eventual failure. Some drivers may forget to replace it during routine maintenance.

2. **Potential for Clogging**

If the breather element becomes clogged with oil or debris, it can restrict airflow, leading to increased crankcase pressure. This can cause oil leaks, gasket failures, or even blowouts in extreme cases. Regular inspection and replacement are critical.

3. **Limited Lifespan in Harsh Conditions**

Vehicles operated in extreme temperatures, dusty environments, or with poor oil quality may experience faster degradation of the breather element. The filter may need replacement more frequently in such conditions.

4. **Mismatch with Aftermarket Modifications**

If your vehicle has been modified with a turbocharger, supercharger, or other performance upgrades, the stock breather system (including the B23124) may not be sufficient. High-performance setups often require upgraded or specialized breather filters to handle increased airflow and pressure.

5. **Cost of Replacement Parts**

While the B23124 itself is affordable, some vehicles may require additional seals, gaskets, or tools for installation. If these components are worn or missing, they may need to be replaced, adding to the overall cost.

6. **Availability and Fitment Issues**

Although the B23124 is widely compatible, there is a risk of purchasing a wrong part if your vehicle s exact model or year is not verified. Using an incorrect part can lead to improper sealing, leaks, or failure to meet emissions standards.

7. **Noisy Operation (In Rare Cases)**

A failing or improperly installed breather element can sometimes cause unusual noises, such as hissing or rattling, due to internal damage or loose components. This is not common with a new, properly installed B23124 but can occur if the part is damaged during installation or if the vehicle has other underlying issues.

---

### **Conclusion**

The Purolator B23124 crankcase breather element is a reliable and cost-effective solution for maintaining your vehicle s emissions compliance, engine health, and performance. Its primary benefits emissions compliance, protection of engine components, and ease of installation make it a worthwhile investment for most drivers. However, it requires regular replacement to function effectively, and its performance can be compromised in extreme conditions or with aftermarket modifications.

For most standard vehicles operated under normal conditions, the B23124 is an excellent choice. It is particularly valuable for owners of older vehicles that are subject to strict smog checks or those who prioritize long-term engine maintenance.

### **Recommendation**

If your vehicle requires a crankcase breather element and the B23124 is listed as the correct part for your make, model, and year, I recommend purchasing it. Here s how to proceed:

1. **Verify Compatibility**

Double-check your vehicle s specifications or consult your owner s manual to ensure the B23124 is the correct part. Purolator s website or a trusted parts retailer can also confirm fitment.

2. **Replace at Recommended Intervals**

Follow the manufacturer s or service manual s recommendations for replacement intervals, typically every 30,000 60,000 miles. If you drive in harsh conditions, consider replacing it more frequently.

3. **Inspect for Damage**

Before installation, inspect the breather element for any signs of damage or contamination. Replace it if it appears worn or clogged.

4. **Install Properly**

Follow the installation instructions carefully to ensure a tight seal. Use any necessary gaskets or seals to prevent leaks.

5. **Monitor Performance**

After installation, monitor your vehicle for any unusual noises, oil leaks, or reduced performance. If issues arise, inspect the breather system and replace the element if necessary.

6. **Consider Upgrades for Performance Vehicles**

If your vehicle has been modified with forced induction or other performance upgrades, research whether an upgraded breather filter is needed to handle increased airflow.

For most drivers, the Purolator B23124 is a practical and necessary part of routine maintenance. Its benefits in terms of emissions compliance, engine protection, and longevity outweigh the minor drawbacks, making it a strong recommendation for eligible vehicles.
